Usefulness of the Symphony Nitinol Stent for Arteriosclerosis Obliterans.

Abstract
The Symphony Peripheral StentTM is a self-expanding stent made of thermal memory Nitinol wire. Stents were implanted in 39 lesions of 32 patients (26 men, 6 women) with atherosclerosis obliterans (ASO). The ankle - arm index (AAI), and vessel diameters evaluated by quantitative angiography were compared before and 6 months after treatment. Symphony Peripheral StentTM implantation significantly improved the AAI from 0.50±0.4 to 0.9±0.2 (pTM is thus a promising choice for patients with ASO. (Circ J 2002; 66: 1000 - 1002)
